Android Camera2图片显示非常慢

Question

I'm working with the android camera2 component and I have problems with understanding why after taking a picture it takes a lot of time before it will be displayed in another activity. Basically what happens is, that when I take the picture and save it, I open up a new activity that should display the picture taken, which it does but after around 5 sec. Then I get these messages in the log:

I would highly appreciate any type of help or suggestion!

It seems you are not using AsyncTask to perform the capture operation. You may refer to this link and check if it helps you.
